It further consists of novel features of construction, all of which will be hereinafter fully set forth.

the parts. rig. 11 isa horizontal section through ig. 4 taken above the bafile plate. Fig; 12 is an enlarged detail showing the connection between' the house "pipe of the water back and the boiler system.

Similar numerals of reference indicate corresponding parts in thevfigures.

Referring to the drawings, 1 designates the frame of my range, which comprises the front plate 2 having a flange 3, the rear plate 4, which as shown is art of a water casing, the end plates 5 an 6 and the top plate 9. t. y

The inner walls of my range are formed of hollow chambers 10, 11, 12 and 13, which are ada ted to be filled with water to increase tile water heating surface exposed to These chambers are 'i'I ig. 9 represents chambers 10, 11 and 12, each to chamber 13 and by the rovision of pipes 14 and 15 between cham ers 11 and 12.

In the top of the fire pot and below the top late 9, I form a coil 16 which is connected y pipes 17 and 18 with the hot water boiler 19 1n the usual manner. fire pot is provided with projections or de- .pressions of preferably thimble form as 20 to increase the radiating surface. The cross connectmg chamber 21 also forms a connection between the chambers 10 and 11 at the same time that it constitutes the front of the lire pot. Upon the back of the range and connected to chamber 13, I place boxes 22 and 23, alternately of different constructions, connecting the first to the chamber 13 and the others to each other by means of ferrules 24 in such manner that there is a complete vertical passage ,25 formed, preferably at each end as shown, for the passage of Water in the direction as shown by the arrows from the chamber 13 to the )ipes 26 and 27 at the top of the back of the range. The boxes 22 are rovided with central apertures 27 X and the oxes 23 are provided with side [a ertures 28, preferably upon each side t ereof, for the'passage of the gases of combustion. Each box is provided with an aperture 29, which, as best shown in Figs. 8 and 9, does not extend through quite the entire length, width or height of the box, but forms a distributingpassage for the hot gases from which passage they are conducted through the central aperture. of one box to the side aperture of the box above, or vice versa, also increasing the heating surface for the water within these boxes. I

- I thus provide a water system comprising the side walls for the heating surface of the range, the back of the range and the vertical back portion in the rear of the range leading up to the position in which the hot water boiler is placed, as shown, and connecting with the vertical pipes 26 and 27, as indicated. VThe water 1s returned through return ipes to the pipes 59 and 60 so that a y'comp ete circulatory system exists at all times.

The hot gases from the fire pot 31 are conducted across the to of the chamber 11 into the air flue 32, 'whic is formed between the The interior of the.

upper surface 3:3 of the bakingoven 34: and y the top plate 9 of the range. The gases are then conducted between these plates 9 and 33 downwardly through the passage 35 formed between chamber 12 and the side wall 34 of the' baking oven, beneath this oven through the assage 36 formed beneath said oven,.vertica1y through the passage 37 formed between .chamber 11 and the side wall 38 of the baking oven, through the opening 39 into the passage 40 formed by walls 41 and 42 and door 43 andthe top 9 ofthe range into the smoke passage 44 thence into the smoke pipe. Door 43 is hinged at 45 and is controlledby rod 46. Within the chambers 10, 11 and 12 and at an other'points desired, may be arranged ba e plates 47 which reuire that the water in its assage through t ese various chambers shall) circulate properly throughout them. I form dust doors 48 in the front of the boxes 22 and 23, as best seen in Figs. 1 and 8. I connect my auxiliary system to the house pl'pe 49 by means of a lateral pipe 49 in Whic is a valve 49X, as seen clearly in Fig. 12. The reason for this connection is that it is necessar at times to increase or reduce the amount olly more water from the city system, which correspondingly forces more water into the main pipe of my radiating system.

The return pipes 59 and 60 of the system connect with any suitable portion as the chambers 10 and 12 of my interconnected Water s stem within the range.

It wil be evident that the het water system may have its outgoing and return pi es connected directly to the hot water boi er, although in such case there wouldbe a drain by the house needs and consequent reduction of temperature in the radiators.

The operation is as follows t-Ihe water is `supplied from the city pressure to the hot water boiler and water back and, as already described, to the house system to keep it up to normal quantity. The cold water is introduced at the lower part of the system within the range at any suitable point or peints and is withdrawn at the upper part ci this System at the top of the upper section or box at the back of the range,

.'lhe door 43 when in place, as shown in Fig. 4, requires that the gases shall pass across the to of the oven and completel around it an enter the smoke iiue through o ening 39 and passage 44, whereas, when t e door 43 has been turned down 'to the position arallel with the top of the oven by means cip rod 46 the gases from the iire pot can pass directly to the smoke iiue without passing around the oven.

It will be evident that various changes may be made by those skilled in the art, which may come within the scope oi my invention and I do not therefore desire to be water in theV system, which former. I do by admittinglimited `in every instance to the exact construction herein shown and described.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent, is

' 1. In a device of the character described, a range having a hot water circulation and back for said range, comprising a plurality of separable communicating water receivers, a hot water boiler lying against said back in indirect communication with said receivers, a hot water coil connected with said boiler, means for causing circulation of hot gases between said receivers, and means for vthe circulation of water. I

2. In a device of the characterdescribed,

.an oven, hollow walls inclosing said oven with interconnecting means forming chambers, a transverse chamber connecting two adjacent chambers and forming the front of the fire pot, hollow boxes at the back of the range and connected with said chambers, and having side and central apertures, and a distributing passage for the hot gases.

3. In a device ofthe character described, a complete intercommunicating water system formed .of hollow side walls for the heating surface of the range, a hollow water back with passages for the products'of combustion extended above the to of the range, a hot Water boiler adjacent t e upper end of said back and in indirect communication with said back7 and ipes leading from the upper portion of sai( back.

4.
